OK abt to trade in the two pools of 6x 1.5tb drives and 6x 1tb drives for 6x 4tb drives.

HGST 4tb NAS still the de-facto standard/way to go? Was trying to be budget minded but I've made my peace spending $900 for 6 of these, any deals arnd?

TIA for any/all input

Funny, I just shipped 2 of those NIB to another member who snagged them from my sale thread :p

If I didn't have to worry about electricity cost at home, for idling my storage drives most of the time I'd have gone with performance models... all RE or Ultratars... heck even the HGST 4TB NAS idle at 7w compared to the WD RED at 3.3 and full-power 5w or less the HGST are power hungry... compared to the WD RE they're saving power :D though!! 84w idle vs 40w (HGST NAS vS WD RED) saves me almost $100/year in the lower power tier, I can't imagine spending more than $100 for all RE... although wish I could warrant the need for high-performance spinners :) I went from 5x2TB RE/SE to 6x5TB RED and 2x2TB RED PRO. Likely swap-out the pro and swap-in 2x more 5tb reds...

Keep an eye on 5TB models for a bit more per-GB as they fluctuated up/down over the last 17 months. You get a bit more performance even on the RED lineup with the larger drives.

You could just get some HGST Ultrastar SAS and :D :D

Don't get me wrong ALL my current drives are all hitachi ultrastar's...love them, thought I saw a deal going on for some 3-4 TB a few weeks back, they maky have been refurb's/open box though, forget the background. Would sure keep 'the Mrs.' happier if I could do this a lil' more economically but it's gonna house all my most precious pics/video's/data that cannot be lost so I want highly reliable/performant (as can be expected out of magnetics) but maybe also w/ pwr in mind, I don't mind running disk spun up all the time though in the name of performance v.s. a watt or two more of power...so yeah there's that. Was just thinking couldn't go wrong w/ HGST 4tb NAS drive but hell maybe I can do better.

That's what I did. I went from servers with 16 * 2TB WD RE4's to 16 of these . I wanted SAS and 4Kn rather than 512e, which limited my choices.
I do kinda want sas...even if I gotta pay a bit more($5-10 a drive maybe), dammit now I am gonna have to go on a 'R&D HD hunt session'

Guide me ohh wise ones.

EDIT, 8TB and rebuild times do scare me a bit...ohh and I only have 6Gbps sas hba's so 'may' have to get a 12G 9300-8i or similar HBA.

@whitey that RE 4TB SAS price seems damn good to me for a new drive. IIRC I've seen them 115-140 used on websites and ebay if you want to go used/refub.

(This is about RE: SATA newer models)
The 5TB RE is insanely expensive but the newer model has 2M MTBF and lower power usage they also come in 4TB but again, more $ than the model you were talking about. This PDF has 2 4TB models, both of which perform > than the one you linked, use less power, and have a higher MTBF -- maybe worth checking out for deals.

http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-800066.pdf

The 5 and 6TB are 4K native the 4TB are 512 native (not emulated).



I'm not sure how the SATA drives perform better, etc... and the SAS cost less and perform worse other than being older drives?

The #s on this drive WD6001FXYZ (6TB) have my droooooling... then again at the price they want you can buy numerous smaller drives and have a bigger array for even > performance for < $ anyway haha.
